Meta Transaction
Here will provides consultation and recommends several vetted relayer solutions, including OpenGSN, Biconomy, and OZ Defender
Support for Gasless Meta-transaction
Our contracts are EIP-2771 compatible so they can support meta-transactions. Our implementation follows the standard provided by @opengsn/contracts.
Relayers
In order to enable gassless transactions, platforms building on TalentLayer must choose a relayer and integrate it into their frontend. Platforms are also responsible for managing whitelisting, since we advise only covering gas costs for a subset of trusted users.
Need help choosing a relayer? We're happy to chat about it! Reach out to us on the "contact" page of the documentation.
Any relayer solutions which are EIP-2771 compatible work with TalentLayer's contracts.
Our team has vetted a few relayer solutions that we recommend supporting:
OpenGSN (V2 or V3)
Implementation:
decentralized, network of relayers, not many but anyone can run their own
need to develop Paymaster contract (probably one for each platform which will have a whitelist of users that can be sponsored)
expensive, multiple extra things done on chain
Biconomy
Implementation:
semi-centralized, network of relayers, many are Biconomy’s but other people can join?
no need to develop any new contracts
OZ Defender
Implementation:
centralized, single relayer, they have the private key
no need to develop any new contracts
need to spin up server or use AutoTask
